How Hardware Startups Use Acoustic Leak Detection for Sealed Products

Episode 106 of Hardware Startups with Fexingo dives into acoustic leak detection — a method used by Tesla, Apple Watch, and medical device startups to find microscopic leaks in sealed enclosures. Lucas and Luna explain how the technique works, why it's faster than traditional dunk testing, and how a startup making waterproof drones used it to cut returns by 65%. They also cover cost, setup, and when a startup should invest in a dedicated chamber versus sending to a test lab. A practical episode for any hardware founder sealing a product against water, dust, or gas.
